Lawyers for the Bali bombers say they still hold out hopes for a further appeal, despite Indonesia's Attorney-General announcing that the trio will be executed early next month.

The Attorney-General's spokesman, Jasman Pandjaitan, went to great lengths to confirm the guilt of the Amrozi, Mukhlas and Imam Samudra before saying that their avenues of appeal were now closed and their executions were set to proceed.

"It will be done in early November 2008, that's it," he said.

But Wirawan Adnan, a lawyer for the bombers, believes the argument that their retroactive convictions which were declared unconstitutional in 2004 have never been properly tested in court.

"We believe there has never been an appeal because there was no trial," he said.

"Their family are still entitled for an appeal because under the law the family has the right to submit an appeal."

The bombers' families are now planning final visits in the weeks ahead.

The Federal Government has updated its warning about travel to Indonesia.

The level of warning remains the same, with the Foreign Affairs Department advising people to reconsider their need to go to Indonesia.
